deprecations:

The ``[libvirt]live_migration_tunnelled`` option is deprecated as of
|
|
Wallaby (23.0.0) release.
|
|
|
|
The "tunnelled live migration" has two inherent limitations: (a) it
|
|
cannot handle live migration of disks in a non-shared storage setup,
|
|
and (b) it has a huge performance overhead and latency, because it
|
|
burns more CPU and memory during live migration.
|
|
|
|
Both these problems are addressed by the QEMU-native support in Nova
|
|
-- this is the recommended approach for securing all live migration
|
|
streams (guest RAM, device state, and disks). Assuming TLS
|
|
environment is setup, this can be enabled by setting the config
|
|
attribiute ``[libvirt]live_migration_with_native_tls``.
